充電方(fang)式(shi)有恒電流(liu)充電和恒電壓充電兩種。
恒流充電(dian)法
恒(heng)流(liu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)法(fa)是用(yong)(yong)調整充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)裝置輸出電(dian)(dian)(dian)(dian)壓或改變(bian)(bian)與(yu)蓄電(dian)(dian)(dian)(dian)池串聯電(dian)(dian)(dian)(dian)阻(zu)的(de)(de)(de)(de)方法(fa)，保持(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)強度不變(bian)(bian)的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)方法(fa)。控制方法(fa)簡單，但由(you)于電(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)可接受電(dian)(dian)(dian)(dian)流(liu)能(neng)力是隨著充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)過程的(de)(de)(de)(de)進(jin)行而逐漸下降(jiang)的(de)(de)(de)(de)，到充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)后期(qi)，充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)多用(yong)(yong)于電(dian)(dian)(dian)(dian)解水，產(chan)生(sheng)氣體，使出氣過甚，因此，常(chang)選用(yong)(yong)階段充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)法(fa)。
恒壓充電法(fa)
充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)的(de)電(dian)(dian)(dian)(dian)壓(ya)在全(quan)部充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間里保持恒定的(de)數(shu)值，隨著蓄電(dian)(dian)(dian)(dian)池端電(dian)(dian)(dian)(dian)壓(ya)的(de)逐(zhu)漸升高，電(dian)(dian)(dian)(dian)流逐(zhu)漸減(jian)少。與(yu)恒流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)法(fa)相比，其充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)過程更接近于*佳充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)曲(qu)線。用恒定電(dian)(dian)(dian)(dian)壓(ya)快速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，由于充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)初期(qi)蓄電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)動勢(shi)較(jiao)低，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流很大，隨著充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)進行，電(dian)(dian)(dian)(dian)流將逐(zhu)漸減(jian)少，因此，只(zhi)需簡易控制系統(tong)。
